' Application filed December 21, 1925. Serial No. 76,624.

This invention relates to weather-proof surface coverings and more particularly to that species known in the art as strip shingles, in contradistinction to the conventional units. Shingles ofthetype referred to are customarilylfabricated of flexible material impregnated with bituminous substance and coated with a mineral surfacing suitably embedded or rolled therein to' impart the requisite weather resistant qualities.

An object of this invention is to economically produce strip shingles having a novel and unique exposure outline, which strips,

when laid in staggered overlappin relation, present the appearance of individually scribed, typically illustrated by the accom- .30 panying sheetof drawin and tersely defined With res ect to nove features-as well as scope-in t e subjoined claims.

In the drawings Fig. I, is -a new in plan illustrative of the manner in which my novel shingle strips are severed from standard width material without waste.-

' Fig. II, is,a lan view of a surface covered with shing e strips in accordance with 4 this invention. r p

Fig. III, is a fragmentary plan section 11-,

lustrat-ing the interlocking phase of my novel shinglestripstand,

- Fig. IV, is a sectionalyiew taken as in-' dicated by the arrowed lines IV-I V in 11 carrying out the invent on Lpreferably make use of. standard width flexible, nonporeus and weather-proof, material having "a transverse dime sion suitable to produce, whenlongitudina y. and laterally severed, the shingle strips in staggered relation with: out-fwaste. Such alengthof material is comprehensively designated 5 by dot-and? dash lines in Fig. I, and it is longitudinally severed at 6 by any appropriate means, and transversely out at 7' to afford successive individual' str'p shingles "8 in alternating right-and-left-hand relation.

.The individual strip shingles 8 bein counterparts of oneanotherl will speclfically Outlinethe form of one only to avoid repetitive description. -Accordingly', it, is to be observed that the strip, shingle8 is configured to afford, as best evidenced by the shaded portion of Fi I, an upper straight edge 9 with rectangu arly disposed ends 10; whereas the lower edge isof undulate character prov ding relatively disconnected quasihexagonal points 11, each terminating with a retrovertible tip 12. More specifically set forth, the points 11 are separated from the body portion of the strip shingle 8 by end recessions 13 and an intermediate notch .14 having edges '15 parallel with the upper straight edge 9; Whereas each point 11, is bounded by two reversely directed oblique edges 16, opposed inwardly converging shorter edges 17 ,and a creasing 18 that separates the retrovertible tip 12 therefrom. 30

'The tip 12, it is to be noted, also is bounded by a lower edge 19 parallel with the strip upper edge 9, and inwardly converging side edges 20. Furthermore, the ti 12 1s the counterpart in configuration of t e notch 14 while the recessions 1 3 are complemental an each the half of said notch; or, in other words, any two adjoining recessions 13 equal an individual notch 14;, as will bewell understood on an examination of the drawings.

, Strip shingles 8 of the character described are laid 'as follows:

A starting strip 21 is first attached tothe roof or other surface in any of the well, known ways, whereupon the first or lower row of strip shingles 8'are secured'in end to end abutting relation with the retroverted tips 12 engaged thereunder, as will be easily appreciated from-an examination of Fig.

;II, more particularly. Successive rows of overlap in -,strip shingles 8';a re similarly laid wit it e retroverted .tips 12, passed by way of the notches 14 and adjoining reces sions 13, below the body: portions of the units in the immediately; preceding row, whereupon they are secured in place by nails 22 inaccordance with conventional practice. x At 'this" point it is well to note that the retrovertible tips 12 are cut to taper slightly outwards, and the advantage thereof will be well appreciated from Fig. III,-

portant, as it overcomes the objections in-v cident to parallel sided tips, which do not readily'fiex to inequalities of the surface being covered. Furthermore, when laying shingles having parallel sidedtips subsurface inequalities tend to spread the shingle units and thereby render the insertion of a parallel sided tip very difficult, and in many instances practically impossible. My trapezit'orm tip 12- and complementarily configured notch 14, eliminates all the aforesaid objections; Whereas it is far more readily retroverted along the creasing 18 as the angular corners 23 thereof provide guidance whereby any inaccuracy in foldingwould be readily detected. I

ence to Fig. II of thedrawings, it will be obvious that my novel strip shingles .8, when 1 laid, provide a surface covering which-has the dist nctive appearance of shingles having hexagonal points but spacedat intervals" laterally of the surface covered; whereas .subj acent strip the interlocked connection of the successively laid units is so apparent as not to need further explanation herein, while the substantially two;ply covering phase of this invention is clearly "understandable from Figs. II and IV, more particularly.

Having thus described my invention, I claim j I 1. A weatherproof surface covering composed of aligned strip shingles laid in overlapping relatively staggered rows; ea'ch strip shingle embodying quasi-hegragonal points, an intervening complemental out out p01 tion, and flanking recessions of similar semicontour; and retrovertible portions integral V with said points having inwardly converg-' contou'iggaand trapeziform .retrovertible tips coextensive with each point and having in wardlyi convergingvslde edges, said tips when w retrovertedbeing adapted to interlockthe From the foregoing, as well ason reiter-- out out and adjoining flanking recessions of ith c 1em ce for lateral movement.

In testimony whereof, I have hereunto signed my name vat Maurer, N this 12th GEORGE BITTER.
